This proposal seeks support for deployment of two 8.5 kg NaI(Tl) detectors at the bottom of two IceCube deep ice holes which will be drilled near the center of IceCube/DeepCore array during the austral summer of 2010/2011. Since the forthcoming austral summer season will be the last of the IceCube MREFC project, the University of Wisconsin submitted this proposal through the NSF's RAPID funding mechanism to be able to take advantage of the last 2500-m deep ice holes and communication cables that will already be deployed for the IceCube string of Digital Optical Modules. The proposed NaI(Tl) detectors will be attached to the bottom of these last two IceCube strings and use the string's "special device" power and communication wires to send data to the surface.

该提案寻求支持在两个IceCube深冰孔底部部署两个8.5千克碘化钠（铊）探测器，这两个深冰孔将于2010/2011年南夏季在IceCube/DeepCore阵列中心附近钻取。由于即将到来的南极夏季将是IceCube MREFC项目的最后一个季节，威斯康星州大学通过NSF的RAPID资助机制提交了这一提案，以便能够利用最后2500米深的冰洞和通信电缆，这些冰洞和通信电缆已经被部署用于IceCube数字光学模块串。拟议中的NaI（Tl）探测器将连接到最后两个IceCube字符串的底部，并使用字符串的“特殊设备”电源和通信线路将数据发送到表面。
